i recently had a power surge and my pc started crashing after that, one day it just didnt boot so i started checking what couldve have gone wrong - turns out it was one of my ram sticks that were fried and when i took it out the pc seemed to work fine, but sometimes i get weird freezing stutters and the audio buzzes for like half a second , i suspect it could be the moterboard that was also damaged - id appreciate any help.
